Engineering Organization & Culture

At Bullish we are engineering the institutional standard for the digital asset industry. Our mission is to build a platform where security and compliance are the foundational core requiring a commitment to technical excellence that goes beyond simply delivering code. We operate as a global engineering organization setting a high bar in a demanding environment for those driven to do the best work of their careers alongside world-class peers.

We value engineers who treat development as a craft and own the outcome from concept to deployment. You will be expected to navigate the unknown bring structure to ambiguity and help shape the frameworks and processes that drive our global teams forward. We refuse to compromise on quality and seek problem solvers who thrive on high-impact technical challenges.

The Team: AI & Data Platform

The AI & Data Platform team powers intelligence across the Bullish ecosystemfrom our institutional-grade cryptocurrency exchange to CoinDesks media data and indices businesses. We build the infrastructure that transforms raw data into governed trustworthy assets and deploy AI systems that meet the reliability standards our institutional clients expect.

We operate at the intersection of data engineering semantic modeling and applied AIdelivering solutions across the enterprise spanning the full breadth of Bullish operations from trading floors to compliance.

As we expand our AI capabilities we are building out a robust evaluation and governance layerensuring every AI system we deploy is observable testable and held to the same engineering standards as our trading infrastructure. This is a team where AI is treated as serious engineering not experimentation.

What Youll Do

• AI Systems Architecture: Design and implement production AI systems with emphasis on reliability observability and continuous evaluation. Champion engineering practices that ensure AI outputs are consistent evidence-based and auditable.

• Conversational Analytics: Lead development of natural-language interfaces to business data enabling stakeholders to query complex datasets through governed semantic layers.

• Agent Development: Architect multi-agent systems that coordinate across data sources applying industry best practices for agent orchestration tool use and structured output generation.

• Evaluation & Trust: Build evaluation harnesses and testing frameworks that measure AI system qualityincluding groundedness factual consistency and output reliabilitybefore deployment to production.

• Cross-Functional Collaboration: Work closely with product trading research and media teams to translate complex requirements into scalable AI solutions with clear success metrics.

• Technical Leadership: Mentor engineers establish coding standards and drive architectural decisions that balance innovation velocity with production stability.

• Semantic Layer Partnership: Partner with data engineering to define and enforce semantic models that bridge raw data to AI-consumable formats ensuring business logic is captured once and reused across applications.

What Youll Bring
